MODULE INSTALLATION
All mini modules install through one of the four openings in the
front panel of the RMM4. Each module is installed with the
handle toward the right-hand side of the RMM4 unit. Each
module should be secured with #4-40 x 1/2" screws via
mounting tabs/holes at the four corners of each module. DC
power cable connections, and any other module-to-module
interconnections, should be made to each module prior to
mounting the RMM4 system into the rack. Observe proper
polarity of cable connectors.
RACK MOUNTING
Adequate ventilation is very important in multi-channel installa-
tions. Units should be spaced apart by at least one panel height
wherever possible, and some air movement is advisable in en-
closed rack cabinets. Excessive heat will shorten component
lifeand system performance willbedegradedwithoutproper cool-
ing.
The power supply features a universal input voltage switching
power supply with attached 115 VAC line cord and four
separate DC output cables with polarized 3-circuit connectors.
